The optical design is there only so they can write higher numbers on the box.
AstroMaster 114EQ is marketed as a telescope with 1000mm focal length with 114mm aperture. This by itself attracts many beginners into buying this telescope.
What they don’t know is the 1000mm focal length is created by a corrector lens, which has errors in its shape and placed in the worst place possible in the telescope, the focuser.
The focuser is the most dynamic part of any telescope. It constantly moves while observing, as are a result, the corrector lens gets misaligned constantly. Adding to that, since there are more parts, the telescope is really hard to collimate. This is especially bad for beginners.
The result is a low-quality image that is really not worth the price. You can see major celestials such as Jupiter, Saturn or some details on the Moon, but really nothing worth considering.
